BERNHARD JACOB, OF SELMA, ALABAMA.

SHUTTER-FASTENER.

PECIPIC'ATION forming part of Letters Patent No. 309,059, dated December9, 1884-.

Application filed July 17, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, BERNHARD JACOB, a citizen of the United States,residing at Selma, in the county of Dallas and State of Alabama, haveinvented a new and useful Improvement in Blind-Fasteners, of which thefollowing is a specification.

In the accompanying drawings, illustrating my invention, Figure 1 is aninside view in elevation of a pair of window-blinds with my improvedblind-fastener attached in position thereto. Fig. 2 is a horizontalsection in the line a w of Fig. 1. Fig. 3 isa View of the same, partlyin plan and partly in section. Fig. 4 is a detail bottom View of thetube which incloses the actuating-spring and in part the bolt of myimproved blind-fastener; and Fig. 5 is a broken sectional view in theline gm; of Fig. 2, looking in the direction of the arrow in the latterfigure.

In the figures, A indicates a tube, open at one end and closed at theother, in which is placed a coil-spring, a, with one end abuttingagainst and fastened to the closed end of said tube, while its oppositeend is fastened to a pintle, 6 attached to the inner end of a bolt, B,which is made to move to and fro within the tube in the act of lockingand unlocking the blind-fiistener. The tube A, at its top and aboutmidway of its length, is perforated, so as to form apintle-way, withinwhich the pintle Z) may travel in the act of locking and unlocking thebolt B, said pintle-waybeing from its initial point f, on top of thetube, spirally curved, as at b, in a downwardly and forward directiontoward the open end I) of the tube, and until it reaches the straightpintle portion I) at the bottom of the tube A, and which extends forwardin a direct line toward the open end b of the tube, as shown. Thispintle-way, partly spiral in form and partly straight, as shown, governsthe line of travel of the pintle b, as well as limits the bolt to itsfull forward and rearward throw, the pintle b traveling in said wayduring such act.

The tube A, as clearly shown in Fig. 1, is firmly fixed to afoundation-plate, g, which is secured to one blind, 0, while thebolt-clasp B is fastened to the fellow blind O. The bolt B has alever-plate, as D. This plate has a finger hole or aperture, 6, throughit, as shown, and its lower inner portion terminates in a catch, as att, which, when the blind-lock is in a locked condition, as representedin Figs. 1, 2, and 5, becomes seated in a catch or channel way, 'i, (seeFig. 3,) of a lock-plate, J, which is secured to the window-sill J ofthe window to which the blinds G O are applied.

In operating the blind-lock the operator places his finger in theaperture e of the lever plate D, then presses laterally in the directionof the arrow, Fig. 2, thus forcing the bolt free from its clasp B, andalso compressing the spring a, and moving the bolt laterally to theextent of the straight portion b of the pintle-way, in which the pintleb is by such pressure made to travel, and until the plate D has reachedthe position shown by dotted lines h in Fig. 1. The operator now turnsup vertically the lever-plate D and resumes the lateral pressure uponthe bolt in the direction of the arrow. This act causes the bolt B totravel farther in a rearward direc tion, (indicated by the arrow,) thepintle 1) during such act being made to travel in the curved pintle-wayb until it has reached its seat b at the top of the tube A, which seatis so formed, as shown, in order to automatically hold the pintle btherein when it is once in position, as represented in Fig. 3. In otherwords, having reference solely to Fig. 1, the operator presses upon D,thus shoving it to the left-hand, out of lock with the lock-plate J, anduntil it has reached the dotted lines h. The lever-plate Dis now turnedup vertically and pressed upon laterally until it has reached the dottedlines h, which act further compresses the spring a, the pintle bmeantime traveling in. the spiral pintle-way 1) until it seats itself inits seat If. I would here state that the spring a need not be fastenedperm anently to the pintle b of the bolt B, and when not so fastened thespring will simply be longitudinally compressed, and yet the samemovement of the bolt B in the act of locking be attained.

'Having fully unlocked the bolt, as indicated in Fig. 3, the operator,by drawing down upon the levenplate D, will force the pintle b from itsseat 6, whereupon the spring a, being released from compression, willinstantly force the bolt outwardly from the tube A, and (the blindsbeing closed, as shown) at the same time throw down the lever-plate I)and cause its catch 2' to enter the eatchway i, as clearly I b, and alever-plate, D, with a lock-plate, J, shown in Fig. 5, and thus securelylock the and the grooved tube A, provided with a blinds O 0 together, asrepresented in Figs. 1, spring, a, substantially as and for the purpose15 2, and 3, against all ordinary intrusion or outdescribed. 5 sideeffort to unlock the same.
